How to clean or replace the filter of a dishwasher

Every dishwasher has a filter at the level of its evacuation. It is located at the bottom of the tank. Disassembly of the dishwasher drain filter is done by hand, and does not require any tools. Clean or replace with a similar model or equivalent recommended by the manufacturer if the sieve is clogged with limestone.

Practical advice

  • Slow draining or unpleasant odors when opening the dishwasher door will usually indicate a problem with the filter, just get rid of residue that ends up in the clog. Poor dishwashing can also be a warning sign of a filter problem.
  • If the clogging of the filter is done without difficulty under tap water, a clogging of the sieve by the limestone is more difficult to solve. You can always try to clean the sieve with burning white vinegar, being careful not to burn yourself.
  • Access to the filter is no problem since it is sufficient to loosen the plastic stopper. This assumes, however, that the dishwasher is empty and the lower basket is removed. Do not intervene immediately after stopping the device: wait a good half hour to give it time to cool and do not risk burning your fingers.
  • Wear gloves to clean the filter housing. Indeed, splinters of glass or dishes could risk to hurt you. Use a hook-shaped piece of wire to remove any food debris from the vent pipe.
  • The bottom of the filter is cleaned by simply passing under tap water. You can place the filter assembly (sieve and bottom filter) in a basin of warm water with detergent. Clean the set with a nail brush.
  • Take advantage of the removal of the lower basket to check the proper operation of the rollers and see if nothing hinders their rotation (son wrapped around their axis).
